Sabino Canyon

	Sabino Canyon Sabino Canyon is a significant canyon located in the Santa Catalina Mountains and the Coronado National Forest north of Tucson, Arizona, United States. Sabino Canyon is a popular recreation area for residents and visitors of Southern Arizona, providing a place to walk, hike or ride. Minutes away from the desert are large waterfalls along Sabino Creek with minor bridges constructed over them. Wildlife in the canyon includes a range of animals. Some of which are deer, javelina, skunks, tortoises, rattlesnakes and mountain lions. Like most places in Arizona, there are also owls, and scorpion which are very common in Tucson hiking trails. History and formation The history of Sabino Canyon began with the formation of the Santa Catalina Mountains over 12 million years ago. Around 5 million B.C., the mountains ceased formation around the Tucson valley. Present-day varieties of plant life first appeared between 6,000 and 8,000 years ago, and some of the earliest human occupants of S ...

	Santa Catalina Mountains The Santa Catalina Mountains, commonly referred to as the Catalina Mountains or the Catalinas, are north and northeast of Tucson in Arizona, United States, on Tucson's north perimeter. The mountain range is the most prominent in the Tucson area, with the highest average elevation. The highest point in the Catalinas is Mount Lemmon at an elevation of above sea level and receives of precipitation annually. Originally known by the Tohono O'odham Nation as Babad Do'ag, the Catalinas were later named in 1697 by Italian Jesuit priest Eusebio Francisco Kino in honor of St. Catherine who was the patron saint of Kino's oldest sister. The Catalinas are part of the Santa Catalina Ranger District located in the Coronado National Forest, and also include the Pusch Ridge Wilderness Area. The mountain range is considered a prominent range in the Madrean sky islands, and partially delimits the mountain ranges in the northwest of the sky island region; lower elevation bajadas associated with ...

picture info	Great Depression The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Protected Areas Of Pima County, Arizona Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

picture info	Landmarks In Tucson, Arizona A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols. Etymology In old English the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc.". Starting from approx. 1560, this understanding of landmark was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back or through an area. For example, the Table Mountain near Cape Town, South Africa is used as the landmark to help sailors to navigate around southern tip of Africa during the Age of Exploration. Artificial structures are also sometimes built to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Rivers Of Pima County, Arizona A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

picture info	Geography Of Tucson, Arizona Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Canyons And Gorges Of Arizona A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Molino Canyon Molino Canyon is a steep-sided, boulder-strewn canyon in the Santa Catalina Mountains northeast of Tucson, Arizona, next to the Molino Basin Campground. The canyon is located within the Coronado National Forest, and encompasses a wide variety of flora and fauna, ranging from lush pine forest in the canyon's upper reaches to Sonoran Desert cactus forest in the lower reaches. Catalina Highway was cut into the western side of the lower part of the canyon. At the bottom of Molino Canyon is Molino Creek, a seasonal stream that flows southwest over large granite outcroppings, forming a series of small waterfalls and pools. Stream-flow is greatest in the spring, as the winter snow melts, and during the monsoon season. The banks of the creek are lined with willow, cottonwood and Arizona sycamore trees. The Molino Canyon Vista is located along Catalina Highway in the transition zone between Sonoran Desert cactus forest and oak-studded grassland, one mile south of the Molino Basin Camp ...

	Sabino High School Sabino High is a public secondary education school located in Tucson, Arizona. Located on the northeast side of the city, it is a part of the Tucson Unified School District. The principal is Kevin Amidan. History The school was established in 1972 in response to the boom of Tucson, Arizona's east side in the 1960s and 1970s. It is named after nearby Sabino Canyon. (Contemporary establishments Santa Rita High School and Sahuaro High School have similar facilities.) Starting with grades 9 and 10, it finally had a full graduating class in 1975. This class chose the school colors purple and gold, and chose Sabercats as the mascot. A committee of freshman at Sahuaro who were going to transfer as sophomores into Sabino came up with the choices put up to a vote of all of the incoming sophomores. The other option was maroon and silver, with the mascot of the Toros. In the early years of the school, a junior high (grades 7 and 8) was located on the same campus. Sports Sabino has a ri ...

picture info	Reptiles Reptiles, as most commonly defined are the animals in the Class (biology), class Reptilia ( ), a paraphyletic grouping comprising all sauropsid, sauropsids except birds. Living reptiles comprise turtles, crocodilians, Squamata, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean taxonomy, Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern Cladistics, cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile Order (biology), orders, historically combined with that of modern amphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Amphibians Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...
